Scarlet WR-3 Plus is an industrial grade wireless anemometer for multipurpose applications and
long-term environmental monitoring.
WR-3 Plus includes a wireless long-range sensor and a portable datalogger display suitable for both
permanent and temporary installation.
The system measures current/average/maximum wind speed, temperature, wind chill, Beaufort
scale, atmospheric pressure, and historic data graphic in high accuracy with customer selectable
measurement units. Users can receive instant data and wind speed alarm at a distance up to
500-meter radius from the sensor.
WR-3 Plus further supports data logging and can export data in excel format to computers by using
micro USB output.

Sensor & Receiver
Sensor
Wireless Connection
Each sensor has a unique wireless address number that has been pre-paired corresponding to the
receiver display. One sensor can be connected to multiple receivers. Several anemometers can
operate in close proximity without disturbance.

The connection between sensor and receiver goes through Sub-1GHz wireless band (868, 915 MHz).
The signal strength is shown on the receiver MAIN page. The transmission range between the
sensor and the receiver can reach up to 500 meters in a direct line of sight. Inside buildings or
obstacles in between may decrease the transmission range.

Installation
Sensor Installation
WR-3 Plus's sensor bottom cap has a 1/4” threaded hole for installation.
You can use Scarlet’s Magnetic Sensor Mounting Bracket to attach the sensor to any iron/steel surface
and to keep it perpendicular to the ground.
WR-3 Plus’s Receiver Holder Kit comes with an anti-slip display holder with neodymium magnets on
both ends and three pieces of adhesive metal flakes.
1. Peel off the backing paper of the metal flake to reveal the adhesive side
2. Press and stick the adhesive side of the metal flake to the Receiver’s back cover
3. Attach the receiver to the display holder magnetically
You can attach the display holder on any magnetic surface or adhesive the metal flake on the non-mag-
netic surface first before attaching the magnetic display holder.
1. Loosen the clamp
2. Insert the sensor body from the bottom of the clamp
3. Tighten the clamp
4. Apply wind cups on wind sensor bearing
5. Make sure you hear a “CLICK” sound that indicates all parts are locked in place.
6. Attach the bracket on the desire magnetic surface
